基于势博弈的异构编队对地观测卫星任务分配方法OA

A distributed task allocation algorithm based on potential games is proposed to address the complex task allocation problem for heterogeneous formation Earth-observation satellites equipped with diverse observation payloads and required to satisfy varied observation demands.First,a task allocation model is established that accounts for energy consumption and onboard storage constraints,reflecting the characteristics of the formation satellite task allocation problem.A proper potential function is constructed,and the task allocation process is described as a game-theoretic process.A fault-free task pre-allocation algorithm based on potential games is then designed,which effectively solves the task allocation problem while reducing computational complexity.Subsequently,to handle sensor failures on satellites,a task re-allocation algorithm is developed based on the pre-allocation results,enabling effective reassignment of tasks under sensor malfunction conditions.Finally,appropriate simulation scenarios are designed for validation.Simulation results demonstrate that the proposed algorithm improves the real-time performance of task allocation while maintaining solution effectiveness.
